DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 645,827, dated March20, 1900. Application filed August 23, 1899. sea] No. 728,198. (Nomodel.)

To all whom it may concern:

Be it known that I, WI'LLI'AM HOWELL ON- ION, of New Orleans, in theparish of Orleans and State of Louisiana, have invented a new and usefulImprovement in Dumping-Cars, of which the following is a full, clear,and exact description.

One object of my invention is to construct a dumping-car which inoperation does not require extra track-sections or alterations in abridge or track upon which it is to be used.

Another object of the invention is to provide a stop or bumper capableof convenient and expeditious application to a rail at any point in itslength, and to so construct the car that upon striking said stop it willbe automatically dropped to dumping position and a section of the bodyoperated to discharge the load, and also to provide a means for varyingthe inclination of the car-body when the load is to be dumped andsupporting a car at its discharge end while dumping.

A further object of the invention is to provide means for controllingthe movements of the car by a cable and directly utilizing the cable forraising a section of the car-body and causing the cable, in connectionwith the stop or bumper, to incline the car-body suitably for dumpingpurposes.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improved car. Fig. 2 is a plan viewthereof. Fig. 3 is a front elevation of the car. Fig. 4 is a sideelevation of the car in dumping position.

Fig. 5 is a side elevation of a stop or bumper used in connection withthe car, and Fig. 6 is an end view of the stop or bumper shown in Fig.5. a

The running-gear of the car consists of a rear axle 10,'a forward axle11, that is farther removed from the ground than the rear axle 10,connectingbars 12, that are secured upon the upper surface of the rearaxle 10 and to the under surface of the forward axle '11, flanged wheels13, mounted to turn on said forward axle 11, and smaller correspondingwheels 14, mounted to turn upon the rear axle 10.

The body A of the car may be made of any suitable material and may begiven any desired shape. Ordinarily it is rectangular, as shown, andwhen the body is in carrying position it rests practically on theforward axle 11 and upon the rear ends of the connecting beams or bars12, as shown in Fig. 1; but the body A is pivotally connected with theforward axle by means of straps 16 or their equivalents, as shown inFig. 3. The wheels 13 and 14: are adapted to travel upon the rails 15 ofan ordinary track.

Uprights 17 are secured to the front of the body, one at each side, andthese uprights extend from the bottom of the body, above the topthereof, as is particularly shown in Fig. 3. The uprights are connectedat the top by a suitable cross-bar 18 and are sustained at their upperends by braces 19, attached to the outer faces of the uprights and tothe outer side surfaces of the body A. Each upright 17 is provided witha longitudinal slideway 20 in its inner face, and the side edges of adoor 21 enter said slideways, and said ways serve as guides for thedoor, the door being a dumping-door and adapted to have vertical slidingmovement. The upward movement of the door 21 is limited by forming lugs22 on the front face of the door at the bottom, which lugs 22, when thedoor is fully elevated, are brought in engagement withlugs 23, attachedto the inner surfaces of said uprights 17. The door 21 is provided withan opening 24: about centrally between its sides and preferably nearerthe top than the bottom, and at this opening a grooved pulley 25 isjournaled in suitable bearings. Hangers 26 are secured to the outer faceof the uprights 17, and these hangers are horizontal when the body is incarrying position. The hangers are adjustably attached to said uprights.A

shaft 27 is journaled in said hangers 26, and

this shaft is provided at each outer end with a small flanged Wheel 28,the wheels 28 being adapted for engagement with the rails of the trackupon which the car is to travel; The wheels and hangers 26 are adaptedto control the degree of inclination of the body A when the load is tobe dumped, since at that time the wheels 28 will engage with the track,as

shown in Fig. 4:. Therefore the hangers 26 are made adjustable, so thata greater or less dumping inclination may be imparted to the body.

When the track is inclined downward in direction of the loading-ground,a single cable 29 is passed under the pulley .25, carried by the door,and is attached by an eye 30, or its equivalent, to the upper centralportion of the back of the car-body, and the said cable is carried to anengagement with a drum 31, situated somewhat adjacent to the place wherethe load is to be dumped, as shown in Fig. 4; but if the track is leveltwo cables will be used, the cable 29 to draw the loaded car to thedumping-ground, and a second ea-- ble, which may be attached to the backof the car, to return said car to the loading-ground.

Two bumpers or stops B are employed in connection with the car. Each ofthese bu mpers or stops consists of an inclined body 32, adapted to belocated over a rail of a track, a clamp 33, which extends downward fromthe body near its higher end, the jaws of the clamp being adapted toengage with a rail, as shown in Fig. 6, and a second clamp 34, ofsimilar construction to the clamp 33, which clamp 3i forms the underportion of the lower part of the stop or bumper. Both clamps areprovided with suitable ad j Listing-screws 35.

In operation the bumpers or stops are secured upon the rails 15 ofthetrack at or near the point where the load is to be dumped, the higherends of the bumpers or stops facing the car. After the car is loaded itis drawn to the dumping-ground by winding up the cable 29, and when thecar reaches the dumpingground the front wheels will engage with thebumpers or stops B. The cable is then still further wound, thus drawingthe front of the ear downward until the guide-wheels BSengage with thetrack, and by continuing to wind upon the cable 29 said cable by reasonof its engagement with the pulley 25 will cause the door 21 to slideupward, and consequently the load will be dumped. When the load isdumped, the cable is slackened, and if the track be inclined the car indescending 'the incline will cause its guidewheels 28 to travel up theinclined surfaces of the stops or bumpers B, thus insuring the body ofthe car being restored to its normal position, and as the cable 29 isslackened the door 21 automatically closes.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a dumping-car, a running-gear, a dumping-bodymounted to tilt on the front end of said gear, a cable secured to therear and free end of said body, stops adapted to engage with the car,and guide-wheels at the dumping end of the body, said wheels beingadapted to limit the inclination of the body and restore the body to acarrying position after having been dumped.

2. A dumping-bodyprovided with aslidiug door in its dumping end, and adraft device secured to said body and connected with the door whereby toslide the latter, as set forth.

Adumping-body,adumping-doorforthe body, a draft device connected withthebody, said draft device serving also to operate the door and assist ininclining the body, and

means for limiting the inclination of said body.

4. In a car, a dumping-body, a dumpingdoor, a stop for thesupporting-wheels ofthe car, a draft-cable attached to the body andcontrolling the movement of the door, and

guide-wheels at the dumping end of the body,
